Yes, the "horns", not the shifters. I know that a lot of road bikes have shifters on aerobars and such, but I'm referring to bar end "horns" on mountain bikes. Way way back in the day, they seemed to be uber cool and everyone had them. Then suddenly they disappeared and now I never see them in use anymore. Yet oddly enough, big companies like Easton and Cane Creek are manufacturing them out of composite materials.
